High-yield cultivation technology of Agrocybe aegerita

Maybe many people who grow plants, vegetables or fungi like to get high yields, so that we can earn more income. So how can tea tree mushrooms achieve high yields? We must work hard on the cultivation technology. Today I will tell you about the high-yield cultivation technology of tea tree mushrooms:

Breeding excellent strains

At present, there are many tea tree mushroom strains, such as tea tree mushroom-1, tea tree mushroom-3, tea tree mushroom-5 selected by Sanming Fungi Research Institute, and AS78.AS982 in Jiangxi. Our region mainly promotes tea tree mushroom-3 and tea tree mushroom-5, which are suitable for both fresh market and dried. But no matter which strain is selected, the mycelium of the fungus is required to be thick and thick white. It is normal for the original species and the cultivated seed material to grow small fruiting bodies like Flammulina velutipes. However, if the mycelium is sparse, weak and thin, the material is not eaten thoroughly, there are variegated spots or yellow water, etc., it is not suitable for use.

Cultivation season

Since tea tree mushrooms are resistant to high temperatures and low temperatures, they can be cultivated all year round in our region. However, the yield and quality of tea tree mushrooms are different in different seasons. Therefore, in order to achieve high yield and high efficiency in tea tree mushroom cultivation, it is necessary to choose the right cultivation period. According to cultivation experiments in various places, spring or autumn planting is suitable, especially spring planting has a higher yield. In production, it is generally arranged that the temperature in spring rises to 20℃ and the temperature in autumn drops to 25℃ for mushroom production. Therefore, the suitable period for spring planting in our region is January-February for bag making and fruiting in April-May, or September-October for bag making and fruiting in November-December.

Mushroom bag production

The culture medium formula is: ① 36.5% sawdust, 36.5% cottonseed husk, 25% wheat bran or rice bran, 1% light calcium carbonate, 1% sucrose; ② 78% cottonseed husk, 20% wheat bran or rice bran, 1% gypsum, 0.5% sugar, 0.5% lime.

The production of mushroom bags is carried out according to the above formula according to the quantity required for production. The raw materials are required to be fresh, free of mildew and pests, and the mixing materials should be uniform. The cotton seed shells can be pre-wetted in advance, and the moisture content of the culture medium should be controlled at about 65%. Use low-pressure polyethylene plastic bags with specifications of 17cm×35cm×0.05cm, each bag is filled with about 0.35kg of dry materials, the height is 14-15cm, the filling is moderately tight, and an inoculation hole with a diameter of 2-2.5cm and a depth of 8-10cm should be reserved in the middle. Level the material surface, put on the collar in time and plug it with cotton (it can also be tied with hemp rope or braided wire), and then sterilize it at normal pressure. Generally, the temperature is increased to 100℃ within 4 hours and maintained for 10-14 hours. The tea tree mushroom has a weak ability to resist miscellaneous bacteria, so the sterilization must be thorough, and the production process must strictly prevent the mushroom bag from being pierced or worn to prevent contamination by miscellaneous bacteria. To prevent the bacteria bag from being punctured, the "double bacteria bag" method (two plastic bags put together) can also be used to make the culture bag.

After the culture medium is sterilized, it can be inoculated only when the temperature of the culture medium drops below 30℃. The inoculation box or inoculation room should be completely disinfected, and the inoculation amount is 30-40 bags per bottle (bag). When inoculating, part of the strain should be inoculated into the holes reserved when bagging, and part should be left on the surface of the material to accelerate the spawning and mycelium cover. After inoculation, the culture should be kept away from light. The mycelium of Agrocybe aegerita is slow to recover from feeding, and is prone to bacteria and insect pests. Therefore, after inoculation, attention should be paid to the cleanliness, drying and ventilation of the culture room to prevent the influence of high and low temperatures and promote uniform production of mycelium. And check frequently. If any bacteria-contaminated bags are found, they should be moved out in time to prevent them from spreading. Generally, the mycelium can fill the bag 30-40 days after inoculation.
